down to beautiful santa clara, the magnolia science academy, where the principal tells me they will be celebrating the computer science education week next week, well a pretty chilly day below freezing in the morning and only a high of 50 weather school is out in santa clara at the magnolia science academy tomorrow. tomorrow we have a big ridge of high pressure off to the west just feeding in that arctic air. the jet stream is dipping as far south as mexico. over the next couple of days we'll see the jet stream continue to be to the south. we'll be on the cold side of things and then see a little area of low pressure swing by to our north and west. as that happens, we'll get a chance of showers. but not just rain showers. in the north bay, friday night the snow level will drop all the way down to 1,000 feet. and gradually climb back to about 2500 feet by saturday morning. bottom line, many of our higher hilltops that's you mount diablo, you mount hamilton, that's you mount tam even may see a little bit of white when the sun comes out on saturday morning and saturday afternoon. so what
